【摘要】：为了确保重载交通高速公路路面具有安全、快速行驶的功能,并能长期保持路面结构的耐久性,新东名(东京-名古屋)高速公路71%的路基段和所有的隧道内均采用了复合式路面。由连续配筋混凝土板与高性能沥青铺装层组成的复合式路面,以往曾在多条路段采用,通过对这些路段的长期使用情况调查得知,复合式路面车辙的发展,不到通常沥青路面的一半,证明复合式结构提高了路面的耐久性;复合式路面裂缝发展较沥青路面慢,裂缝率达到20%的时间:沥青路面为15年,而复合式路面为25年;复合式路面的维修周期是沥青路面的1.5倍,对重载交通的路面,若考虑维修因素,复合式路面是一种经济的路面结构。此外,由于维修周期的延长,减少了沥青路面废料的产生,可减少对环境的影响。
[Abstract]:In order to ensure that heavy traffic highway pavement has the function of safe, fast driving, and can maintain the durability of the pavement structure for a long time. The roadbed section and all tunnels of Xindong Ming (Tokyo-Nagoya) expressway 71% are made of composite pavement, which is composed of continuous reinforced concrete slab and high performance asphalt pavement. It has been used in many road sections in the past. Through the investigation of the long-term use of these sections, the rutting development of composite pavement is less than half of that of the usual asphalt pavement, which proves that the composite structure improves the durability of the pavement. The crack development of composite pavement is slower than that of asphalt pavement, and the crack rate reaches 20%: the asphalt pavement is 15 years, and the compound pavement is 25 years; The maintenance period of composite pavement is 1.5 times of that of asphalt pavement. If maintenance factors are taken into account, composite pavement is an economical pavement structure. Reduce the production of asphalt pavement waste, can reduce the impact on the environment.
